Welcome Promotions
When you sign up with Rainbet, you can choose a welcome bonus that matches your preferred play style. We think this is a better system than splitting the bonuses between “Casino” and “Sports”.
Wager Welcome Bonus - Up to $2,100
The first option is a higher-value welcome package that comes with wagering requirements (40x). You get a deposit bonus for each of your first three deposits and receive a number of Free Spins on top.
Here’s how it works:
1st Deposit - 100% + 20 Free Spins
2nd Deposit - 100% + 20 Free Spins
3rd Deposit - 100% + 20 Free Spins
With the maximum deposit amount per deposit being $700, you can claim a total bonus of $2,100 across your first three deposit.
No-Wager Welcome Bonus - Up to $700
If you don’t want to be dealing with wagering after claiming your bonus, you can opt for the no-wager welcome bonus instead.
It’s a 100% bonus which you can redeem as you bet. Redemption used the following formula:
Wager Amount x 1% x 20% per bet
For example, a $10 wager would unlock $2 of your bonus funds from your 100% deposit bonus. Keep playing to unlock more of your funds and have even more cash to play with.
The minimum deposit amount for this bonus is €30, while the maximum 100% bonus you can claim is $700.

Ongoing Rainbet Rewards
Rainbet is known to offer a great range of constant rewards that players can make the most of daily and weekly. The system can be quite confusing, so allow us to explain it to you.
Rakeback
Rakeback is a reward that gives you a percentage of the bet value back. The amount of rakeback you can get is based on the following formula:
bet amount x house edge x 0.05
So, for example, if you bet $100 and the house edge is 95%, you’ll earn 95 x 0.05 in rakeback, which is $4.75.
Rakeboost
There are a number of ways that you can activate the Rakeboost feature at Rainbet, which increases your rakeback rate by 15% while active.
The first way to activate the Rakeboost feature is by creating your account, and it will be active for the first 24 hours of being a member.
Daily, Weekly, and Monthly Bonuses
The Daily Bonus is the amount of rakeback you have qualified to receive for that day, while Weekly Bonuses and Monthly Bonuses are based on how much you’ve qualified for in the last week or month respectively.
Daily Calendar
Calendar rewards are based on the expected value you generate throughout the day, week, or month. The amount you receive essentially depends on how much you wager and in which games.
Because there is no maximum amount you can receive, you will always be rewarded appropriately for the amount of time and money you spend across the site.
As well as these rewards, you can also receive keys to open chests and Rank Rewards as you level up the VIP tiers.
$20,000 Weekly Raffle
The $20,000 Weekly Raffle is an ongoing promotion at Rainbet where you can earn tickets for every $500 wagered across the site’s products. Increase your chances of winning a share by playing as much as you can.
The $50,000 is shared equally between the 50 lucky ticket holders, which means $400 in additional funds if you’re one of the lucky winners.
To see how many tickets you currently have, you can click on the “Your Tickets” button on the Raffle page, which is accessible by clicking the “$20,000 Weekly Raffle” button in the top right-hand corner of the page.
There’s also a timer so that you know how long is left until the next Raffle draw. The draw takes place every Saturday.
Rainbet VIP Club
Become a member of Rainbet’s VIP Club to access premium rewards, such as rakeback, daily, weekly, and monthly bonuses, plus personalised support for an exceptional gaming experience.

These games can also be filtered and sorted by the same options you have in the slots section, including Providers, Alphabetical, New Releases, Random Games, or Originals.
Baccarat
Baccarat remains one of the most popular table game options alongside blackjack and roulette. On this site, there are 17 options to choose from in total, including popular titles like Speed Baccarat, Bac Bo, Mega Baccarat, and Fortune Baccarat 6.
Roulette
It wouldn’t be much of a casino site without roulette games, of which you can find 30 alternatives to choose between in the dedicated “Roulette” section of the site.
Popular options in this area include Evolution’s “Lightning Roulette”, Pragmatic Play’s “Mega Roulette”, and Pragmatic Play’s “PowerUp Roulette”.

Rainbet Case Opening
In the “Case Open” game mode in Rainbet NFT and CS2, players can unlock Cases containing cosmetic items like stickers, weapon skins, and more, which can be used in Counter-Strike. A number of variables, including chance and rarity, decide what goes into these Cases.
Counter-Strike weapon and cosmetic cases have always been a popular gambling option within the Esports betting community, so having this option alongside casino games, sports betting, and Esports betting truly completes the site and rounds things off.
Case Battles
Take your Case Open experience to the next level by battling it out with other players who enjoy betting on CS cosmetics which have real-world values.
Buy into a battle, which can be 1v1, 2v2, or groups, but paying the buy-in amount. If the total value of the random cosmetics you gain is worth more than the total value of the cosmetics your opponent(s) gain, then you take the entire loot.

Click on the green “Wallet” button at the top of the page when you need to add more funds to your account or withdraw your winnings if you have been lucky enough.
